Can you replace key tabs?

My daughter spilt water into her Packard Bell Easy Note lap top.
She tried to dry it out using an hair drier, in doing so melted several keys.
The top of the keys that are warped are easily removable, Question is, can I get a new set of key tabs.
We removed the damaged key tops and were able to replace them easily using the letter "n" as an experiment.

Thanks for your help
